trigger not firing please help on event object

senario is that, if we create a new event on a account object then it should update the description field of account.  But it is not wokring. 
  
trigger event on Event (after insert) {
set<id> ids=trigger.newmap.keyset();

map<id,event> newevents =new map<id,event>();

 for(event e1:trigger.new)
 {
 if(((String)e1.whatid).startsWith('001')) {
 newevents.put(e1.id,e1);
  }
 }
// account acc=[select id,name,description from account where id in:newevents.keyset()];
 
 for(account a1:[select id,name,description from account where id in:newevents.keyset()])
 {

a1.description=newevents.get(a1.id).location;
update a1;
 
}
}

Prasanth,

While copying ids you are copying event ids not account ids, following is the updated code 
trigger event on Event (after insert) {

map<id,event> newevents =new map<id,event>();
List<Account> acclist = new List<Account>();
 for(event e1:trigger.new)
 {
    if(((String)e1.whatid).startsWith('001')) {
     newevents.put(e1.whatId,e1);
    }
 }
// account acc=[select id,name,description from account where id in:newevents.keyset()];
 
 for(account a1:[select id,name,description from account where id in:newevents.keyset()])
 {

a1.description=newevents.get(a1.id).location;
acclist.add(a1);
 
}
update acclist;
}

Hope it helps you.

Thanks,
Anjith

The following code works fine for me...
try this code
  
trigger changedescription on Event (after insert) {

    map<id,event> newevents =new map<id,event>();
    List<Account> acclist = new List<Account>();
     for(event e1:trigger.new)
     {
        if(String.valueOf(e1.whatid).startsWith('001')) {
         newevents.put(e1.whatId,e1);
        }
     }
     
     for(account a1:[select id,name,description from account where id in:newevents.keyset()])     {
        a1.description = newevents.get(a1.id).location;
        acclist.add(a1);
    }
    if(acclist.size()>0){
        update acclist;
    }
}
